摘要:
A printing system having an ink tank for storing ink, the ink tank having a housing having an ink feeding port formed through a first surface for feeding ink therethrough, and a second surface opposite the first. An ink absorbing member is accommodated in the housing, is a porous member having a three-dimensional net-shaped structure molded of a composition comprising a condensate of (i) a compound having an amino group and (ii) formaldehyde, and has a first surface facing the ink feeding port. An alleviating member having more resilience than the ink absorbing member is disposed between the ink absorbing member and an ink outflow portion formed through the ink feeding port and alleviates pressure applied by the ink outflow portion against the ink absorbing member. Both the alleviating member and the ink absorbing member are deformed by compression against the ink outflow portion. A compensating member having more resilience than the ink absorbing member is disposed between the ink absorbing member and the ink outflow portion and applies a functional force to the ink absorbing member corresponding to deterioration of properties of the ink absorbing member. Another ink absorbing member having more resilience than the ink absorbing member is disposed between the ink absorbing member and the ink outflow portion.

A length of a melamine foamed block to be accommodated in an ink tank housing as measured in the longitudinal direction is dimensioned to be larger than a length of the ink tank housing as measured in the longitudinal direction. Thus, while the foamed block is accommodated in the ink tank housing, it is compressed in the direction orienting toward an ink feeding port from which ink is fed to a printing head, i.e., in the ink feeding direction. Consequently, the ink retaining force induced by the capillary force is not intensified in the compressing direction of the melamine foamed block, resulting in an ink feeding capability of the printing head being improved. On the contrary, the ink retaining force effective at a right angle relative to the compressing direction of the melamine foamed block is intensified.

An ink tank for storably receiving ink therein comprises a housing having an ink feeding port to allow ink to be storably received therein and fed through the ink feeding port, an ink absorbing member accommodated in the housing for retaining ink, the ink absorbing member being a porous block with a first surface facing the ink feeding port and having a three-dimensional net-shaped structure, and comprising a foamed block molded of a condensate of a compound having an amino group and a formaldehyde as base materials. The ink absorbing member is pressed toward the ink feeding port by pressing substantially an entire area of a second surface of the ink absorbing member opposite its first surface.

An ink tank includes a housing and an ink absorbing member accommodated in the housing. The ink absorbing member is constructed using a water jet cutter. The ink absorbing member is a thermosetting foamed block having a porous three-dimensional divergent circuit network; the foamed block is molded of a condensate comprising a compound having an amino group and a formaldehyde. The foamed block is formed for placement in the housing by actuating the water jet cutter and worked by actuating the water jet cutter to provide slits or holes in the ink absorbing member different from pores of the foamed block.
摘要:
An ink absorbing member is inserted in an ink tank housing which at least partly has a transparent portion. Used as this ink absorbing member is one having a reflection density after ink removal which is close to the reflection density of a melamine foam before ink injection. The amount of ink remaining in a cartridge of such a construction can be detected, for example, by a separate line sensor. The results of detection by the line sensor can be displayed by a remaining ink amount indicator provided on a control panel of the printing apparatus.

An ink container includes an ink storing portion for storing ink; an ink supplying portion for supplying ink to a recording head portion; an air vent for taking the atmospheric air into the ink container; and a hollow tube, one end of which opens to the atmosphere at the air vent, above the liquid level of the stored ink, and the other end of which opens within the ink container adjacent to the bottom portion of the ink container.
摘要:
An ink absorber is housed inside a housing of an ink tank and is capable of retaining ink. The ink absorber has an outer surface equal to or corresponding to a shape of an internal surface of the housing and is made of a fiber material obtained by compressing a fiber body and thermally molding at least a surface thereof. An ink tank is comprised of the ink absorber and the housing. An ink jet cartridge is comprised of the ink tank and a print head. The ink absorber has an outer surface equal to or corresponding to a shape of an internal surface of the housing before being inserted into the housing. The ink absorber comprises a fiber material, and is formed by compressing a fiber body and thermally molding at least a surface thereof.

An ink container includes an ink absorbing material accommodating chamber for accommodating an ink absorbing material for retaining ink to be supplied to a recording head; an ink supply opening connectable with said recording head to supply the ink to the recording head from said accommodating chamber; an air vent portion for fluid communication between said accommodating chamber with ambience; wherein said air vent portion has an inside opening in fluid communication with an inside of said accommodating chamber, an outside opening open to the ambience, and a fluid communication path in fluid communication with said inside opening and outside opening; wherein said outside opening takes, when-said container is mounted on an apparatus with which it is usable, a position lower than that taken by said inside opening.
摘要:
A sealing method for an ink container having a front side, a rear side, a bottom side, an upper side and two lateral sides, and having an ink supply port for supplying ink to a recording head portion and an air vent for fluid communication between an inside of the ink container and ambience. A seal member is mounted on a first one of the sides and on a second one of the sides continuous with the first side, the seal member having a width larger than a width of the first and second sides. A portion of the seal member is inwardly folded beyond the width of the first side. A portion of the seal member is outwardly folded beyond the width of the second side. The inwardly folded portion of the seal member is heat-sealed to a side of a packaging bladder for accommodating the ink container.
摘要:
A manufacturing method for an ink container mountable to an ink jet apparatus in which the ink container includes an ink supply port, an air vent which has an inside opening which opens to an inside of the ink container, a groove functioning as an outside opening and extended from the inside opening, and a wall except in a region functioning as an outside opening around the groove. According to the method, a seal member is positioned to a position corresponding to the ink supply port and the air vent, and the wall is thereafter collapsed through the seal member by a welding horn. By virtue of this method, a cover is thus provided in the wall above the groove to form a fluid communication path for fluid communication between the inside opening and the outside opening, with simultaneous welding of the seal member by heat.
